They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0043] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0044] refer to Figures 1-3 An embodiment of the present invention shows an easily adjustable grid screwdriver, including a base 1, a bidirectional screw 2, at least one guide rod 3, and two screwdriver assemblies 4;

[0045] The bidirectional screw 2 is rotatably mounted on the base 1, and the bidirectional screw 2 has two threaded sections with opposite directions of rotation (not marked in the figure); the guide rod 3 is fixedly mounted on the base 1, and the guide rod 3 is arranged parallel to the bidirectional screw 2; two screwdriver assemblies 4 are respectively threadedly connected to the two threaded sections on the bidirectional screw 2, and the screwdriver assembly 4 is slidably connected to the guide rod 3; the screwdriver assembly 4 includes a screwdriver head 421.

[0046] The bidirectional screw 2 is rotatable on the base 1 but relatively fixed in the axial direction. When the bidirectional screw 2 is rotated, the two screwdriver assemblies 4 move away from or closer to each other because the threads on the bidirectional screw 2 have opposite directions. Thus, the grid screwdriver of this embodiment only needs to rotate the bidirectional screw 2 to move the positions of the two screwdriver assemblies 4 simultaneously, thereby adjusting the distance between the two screwdriver heads 421. Unlike the prior art, it is not necessary to adjust the two screwdriver heads 421 separately, making the operation more convenient and faster.

[0047] In some embodiments, for further ease of operation, such as Figure 1 and Figure 2 As shown, a rotating wheel 5 is fixedly mounted on the bidirectional screw 2. The rotating wheel 5 is located between two threaded sections and is rotatably mounted on the base 1. The bidirectional screw 2 can be rotated by rotating the rotating wheel 5.

[0048] Specifically, the base 1 is provided with a first mounting hole 11 for the bidirectional screw 2 to pass through, and the base 1 is also provided with a mounting cavity 12 for mounting the rotating wheel 5. The first mounting hole 11 passes through the mounting cavity 12. The rotating wheel 5 is annular and is sleeved on the bidirectional screw 2. The rotating wheel 5 is provided with a first through hole 51 opened radially, and the bidirectional screw 2 is provided with a first threaded hole 21 opened radially. A first screw 7 is provided in the first through hole 51 and the first threaded hole 21. The first screw 7 is threadedly connected to the first threaded hole 21 to fix the rotating wheel 5 and the bidirectional screw 2.

[0049] Thus, the rotating wheel 5 prevents the bidirectional screw 2 from moving axially on the base. During assembly, the rotating wheel 5 is first placed in the mounting cavity 12, then the bidirectional screw 2 is passed through the first mounting hole 11 and the rotating wheel 5, and finally the bidirectional screw 2 and the rotating wheel 5 are fixed with the first screw 7.

[0050] In some embodiments, such as Figure 2 and Figure 3 As shown, the screwdriver assembly 4 includes a screwdriver base 41 and a screwdriver body 42; the screwdriver base 41 is provided with a second through hole 412, a second threaded hole 411 and a second mounting hole 413, the second through hole 412 and the second threaded hole 411 are arranged parallel to each other, the second through hole 412 and the second mounting hole 413 are at a certain angle, the second through hole 412 is sleeved with the guide rod 3, and the second threaded hole 411 is threadedly connected with the bidirectional screw 2; the screwdriver body 42 is rod-shaped, the screwdriver body 42 is disposed in the second mounting hole 413, and the screwdriver tip 421 is disposed at the end of the screwdriver body 42.

[0051] The above-mentioned solutions are specific, such as Figure 3 As shown, the screwdriver holder 41 is also provided with a third threaded hole 414 communicating with the second mounting hole 413. A second screw 8 is provided in the third threaded hole 414, and the end of the second screw 8 abuts against the screwdriver body 42 in the second mounting hole 413 to fix the screwdriver body 42 in the second mounting hole 413. In this way, the position of the screwdriver body 42 in the second mounting hole 413 is adjustable, making it convenient to adjust the screwdriver heads 421 on the two screwdriver bodies 42 to be aligned in height. Moreover, the screwdriver body 42 is detachable from the screwdriver holder 41, and different screwdriver bodies 42 can be replaced.

[0052] More preferably, the screwdriver body 42 has screwdriver tips 421 with different structures at both ends, which facilitates matching with optical elements with different screwing structures; such as Figure 3 As shown, in this embodiment, the screwdriver tips 421 at both ends of the screwdriver body 42 are a flat screwdriver tip 421 and a cylindrical screwdriver tip 421, respectively.

[0053] In some embodiments, for ease of installation of the guide rod 3, such as Figure 2 As shown, the base 1 is provided with a third mounting hole 13 for the guide rod 3 to pass through. The base 1 is also provided with a fourth threaded hole 14 communicating with the third mounting hole 13. A third screw 9 is provided in the fourth threaded hole 14. The end of the third screw 9 abuts against the guide rod 3 in the third mounting hole 13 to fix the guide rod 3 in the third mounting hole 13.

[0054] Preferably, to make the force on the screwdriver assembly 4 more stable, such as Figure 1 As shown, there are two guide rods 3, which are symmetrically arranged on both sides of the bidirectional screw 2.

[0055] In some embodiments, to facilitate turning the crosshead screwdriver, such as Figure 1 andFigure 2 As shown, a cylindrical screw-on portion 6 is provided on the top of the base 1, and the outer peripheral wall of the screw-on portion 6 is provided with friction patterns 61. Two screwdriver assemblies 4 are symmetrically arranged on both sides of the screw-on portion 6.

[0056] Thus, when using it, there is no need to grip the guide rod 3, the bidirectional screw 2, or the screwdriver assembly 4 (that is, there is no need to grip the grid bracket). You can grip the screwing part 6 with just your index finger and thumb, so that you do not need to flip your wrist when turning it multiple times, making it convenient and quick to screw.

[0057] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0058] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
